Yes, B will also be forced into a 1 element array (with ForceArray => 1). But IMO that is the way it should be. It's consistant.

    Thanks. I'm trying to cope in a general way with these situations:
    use strict; use warnings; use XML::Simple;use Data::Dumper; my $file = './test.xml'; my $a = ['x','y']; my $a1 = [$a]; my %tmp = ( A =>$a1, B => 'z'); XMLout(\%tmp,outputfile=>$file,noattr=>1); %tmp = %{XMLin($file,forcearray=>['A'],noattr=>1)}; print "----------\n"; print $tmp{B}."\n"; print $tmp{A}[0]->[0]."\n"; $a = ['x']; $a1 = [$a]; %tmp = ( A =>$a1, B => 'z'); XMLout(\%tmp,outputfile=>$file,noattr=>1); %tmp = %{XMLin($file,forcearray=>1,noattr=>1)}; print "----------\n"; print $tmp{B}."\n"; print $tmp{A}[0]->[0]."\n"; $a = ['x']; $a1 = [$a]; %tmp = ( A =>$a1, B => 'z'); XMLout(\%tmp,outputfile=>$file,noattr=>1); %tmp = %{XMLin($file,forcearray=>['A'],noattr=>1)}; print "----------\n"; print $tmp{B}."\n"; print $tmp{A}[0]->[0]."\n";
    That outputs:
    ---------- z x ---------- ARRAY(0x653930) x ---------- z Not an ARRAY reference at tmp1.pl line 31.
    I can only think of evaluating ref($tmp{A}) and ref($tmp{B}) to decide how to operate, since in my code $tmp{A} is an array reference to an array that can have a single element made by an array reference to a single-element array itself, and $tmp{B} is instead a scalar. I guess I'm missing something...
